Abstract

The utility model discloses a relief valve silencer is used in chemical plant, characterized by, include superimposed a plurality of layer of barrel in proper order, be provided with decibel tester in the middle of the barrel of the superiors, every be provided with rotatable ring on the barrel inner wall, evenly be provided with a plurality of baffle on the ring inner wall, it is adjacent through screw thread swing joint between the barrel. The utility model discloses the beneficial effect who reaches: the quantity of barrel can be adjusted according to the noise elimination sound effect of reality to this device, meets the requirements up to setting up the decibel that detects at the decibel tester of the superiors, the setting of baffle is used for upsetting sound wave and air current to the noise reduction, the baffle of slope is possibly rotatory because of the former of air current therefore production at the in -process of eliminating the noise to can improve the effect of noise elimination.

Description

Chemical plant safety valve silencing apparatus
Technical field
The utility model relates to a kind of chemical plant safety valve silencing apparatus, belongs to noise elimination equipment technical field.
Background technique
Chemical plant safety valve silencing apparatus is a kind of silencing apparatus, be mainly used in electric power, chemical industry, safety valve in the industries such as metallurgy, effective noise elimination of the high temperature and high pressure steam discharge of Pcv valve and exhaust steam valve, for boiler safety door and exhaust steam valve, it can look at is a constituent element of pipeline, after Acoustic treatment is made in inside, generation and the propagation of noise can be weakened, outlet silencing noise amount is made to reach 20 ∽ 30 decibels (A sound level), correspondingly loudness reduces by more than 50%, subjective sensation has positive effect, silencing apparatus is the device of abatement pneumatic noise, installed in the duct or enter, on relief opening, while air-flow passes through, to noise, there is certain consumption.Existing silencing apparatus is because complex structure, weight are large, high temperature oxidation sound absorption filler, high velocity air impacts sound absorption filler, the reasons such as aqueous vapor infiltration sound absorption filler, silencing apparatus is easy to occur that maintenance is frequent, soundproof effect is poor, the situations such as life cycle is short, soundproof effect is poor, and intake and exhaust resistance is larger, air flow property is poor, greatly reduces the reliability of silencing apparatus work.
Model utility content
For solving the deficiencies in the prior art, it is simple that the purpose of this utility model is to provide a kind of structure, the chemical plant safety valve silencing apparatus that durability degree is high.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of chemical plant safety valve silencing apparatus, is characterized in that, comprise the some layers of cylindrical shell superposed successively; A decibel testing instrument is provided with in the middle of the cylindrical shell of the described the superiors; Each described cylinder inboard wall is provided with rotating annulus, circle ring inner wall is evenly provided with several dividing plates; Be flexibly connected by screw thread between adjacent described cylindrical shell.
Aforesaid chemical plant safety valve silencing apparatus, is characterized in that, each described dividing plate is obliquely installed.
Aforesaid chemical plant safety valve silencing apparatus, it is characterized in that, described dividing plate and cylindrical shell all adopt soundproof material.
Aforesaid chemical plant safety valve silencing apparatus, is characterized in that, described dividing plate is provided with equally distributed small sircle hole.
Aforesaid chemical plant safety valve silencing apparatus, is characterized in that, the middle part of described undermost cylindrical shell is provided with suction port.
Aforesaid chemical plant safety valve silencing apparatus, is characterized in that, described undermost cylindrical shell bottom is provided with rubber sheet gasket.
The beneficial effect that the utility model reaches: this device can regulate the quantity of cylindrical shell according to the noise elimination sound effect of reality, until the decibel that the decibel testing instrument being arranged on the superiors detects meets the requirements; The setting of dividing plate is used for upsetting sound wave and air-flow, thus reduces noise; The dividing plate tilted likely produces rotation because of the reason of air-flow in the process of eliminating the noise, thus can improve the effect of noise elimination.
Accompanying drawing explanation
Fig. 1 is the structural representation of this device.
The implication of reference character in figure:
1-cylindrical shell, 2-decibel testing instrument, 3-annulus, 4-dividing plate, 5-suction port, 6-rubber sheet gasket.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, this device is collected in cylindrical shell 1 by the gentle suction port 5 that flows through of noise sent by equipment relief opening, reduce widely after the effect of the small sircle hole of noise on dividing plate 4 and dividing plate 4, tested by decibel testing instrument 2, if still defective, increase the number of cylindrical shell 1 again, until the position that meets the requirements.Owing to being threaded connection between cylindrical shell 1, therefore increase and decrease get up very convenient, simple to operate.
The rubber sheet gasket 6 that cylindrical shell 1 bottom is arranged is for fixed cylinder 1, and the frictional force of rubber sheet gasket 6 is comparatively large, and has certain deformation, can fill up gap, thus ensure the erasure effect of self.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
